iwlwifi: mvm: avoid clearing a just saved session protection id

Browse Source 
When scheduling a session protection the id is saved but
then it may be cleared when calling iwl_mvm_te_clear_data
(if a previous session protection is currently active).
Fix it by saving the id after calling iwl_mvm_te_clear_data.
